    This algorithm aids in patient diagnosis by comparing symptom vectors against a disease matrix. It identifies the most likely diagnosis and ranks disease similarity and symptom importance.

    Area of Science:

    • Medical Informatics
    • Computational Biology
    • Clinical Decision Support

    Background:

    • Accurate patient diagnosis is crucial for effective treatment.
    • Differential diagnosis can be complex and time-consuming.
    • Objective methods are needed to support clinical decision-making.

    Purpose of the Study:

    • To describe a novel algorithm for assisting in patient diagnosis.
    • To quantify the similarity between potential diagnoses.
    • To establish a hierarchical order of characteristic symptoms for diseases.

    Main Methods:

    • Developing a computational algorithm for diagnostic assistance.
    • Utilizing scaled column vectors to represent patient symptoms.
    • Comparing patient symptom vectors against a comprehensive disease matrix.
